测量了六种三元混合物：甲基丙烯酸甲酯(1)+ 2-丁氧基乙醇(2)或二丁基醚(2)+苯(3)、甲苯(3)和对二甲苯(3)在T =(298.15和308.15)K时的实验密度、声速和相对介电常数。超额摩尔体积，超额等熵压缩，和偏差在摩尔极化计算。利用组成二元对的数据，采用Redlich-Kister、Tsao and Smith和Kohler方程，计算了三元体系的上述函数。与其他方程相比，我们发现Redlich-Kister方程可以很好地再现实验过量摩尔体积，而上述三元混合物的过量等熵压缩率和摩尔极化偏差不能用各自的二元贡献来充分计算。
The experimental densities at T = (298.15 to 318.15) K, speeds of sound, and relative permittivities at T = (298.15 and 308.15) K are measured for the six ternary mixtures: methyl methacrylate (1) + 2-butoxyethanol (2) or dibutyl ether (2) + benzene (3), toluene (3), and p-xylene (3). Excess molar volumes, excess isentropic compressibilities, and deviations in molar polarizations are calculated. The above functions of ternary systems were also calculated using the data of constituent binary pairs and employing Redlich-Kister, Tsao and Smith, and Kohler equations. Compared to others, the Redlich-Kister equation has been found to reproduce the experimental excess molar volumes adequately, while excess isentropic compressibilities and deviations in molar polarizations of the above ternary mixtures could not be adequately calculated using the respective binary contributions.
